Interesting OpenSource project that use only a simple RaspberryPI 0 as DVB-S transmitter + RTL-SDR dongle  as receiver. 
This is less expensive DVB-S trasmitter ever developed. 
All the project is by Evariste he is a great developer and member of HAM Radio community ... now we are working togheter to a revision of system with low latency that fit the requirment of drone community .... now the latency is 2.5 second could became 200 ms with a power ampli for real use in outdoor scenario. If some one would join to beta testing of the system are welcome :)
This is the github where you can found the source code of the project .

The receiver is an RTL-SDR standard dongle available on store like amazon or ebay for price less 30 $ . The decode is done using SDR technology the software from decoding is from Pabr the name is leandvb . This is the link .

This software decode DVB-S directly from rtl-sdr stream. It's impressive :)

    @Gregory ,

    the range is only 4 / 5 meter with the wire ... nedd to add a pre ampli + noch filter ... some HAM guys are working on a cheap cirtcuit to add ... with 1 W you can do 10 km or more depend of antenna .

  • This is interesting! What is the transmission range with the simple wire transmitter?
  • Hey this could get pretty interesting! Hummmm

    Jack is not MPEG-2 but H.264 :) And sure the incredible is that si a compliant standard DVB-S not a custom standard ... so it's compatible with standard receiver. The new revision of code that is in src but is not already available in stable version will be a 200 ms of latency and not 2.5 second like the old one revision that already is impressive :) 



  • Easier to send JPEG with no latency than MPEG-2 with all the latency.  Still nifty that the old GPIO with DMA can modulate that much data.

  • Say what??? Awesome! Sign me up! ;-)

  • It is really great, congratz to him. Would the RPi0 have enough power to also store the video in SDCard, at the same time?
